Caption: This Chandra image of Sgr A* and the region around it was based on almost two weeks of observing time. A theoretical model based on these deep data has been produced to help explain why this giant black hole seems to consume so little material. Scientists have also used these data to probe supernova remnants and lobes of hot gas extending away from the black hole. The image also contains several mysterious X-ray filaments.
